Claims. (Cl. 29-3) This invention is directed to fabric or leather covered buckles, buckle bodies and like articles made of covered wire especially wherein the said articles are matle of metal or other material either bent, formed or pressed to desired outline.

This invention relates particularly to forming dies and mechanism for cutting fabric covered wire rod to length and forming buckles and the like.

An object of this invention is to provide forming dies incorporating a pair of concurrently actuating bodily shiftable die members in which a bar is continuously under control from the start to the finish of all the bending, ejecting and collecting steps.

Another object of this invention is to provide a second step inbending device including parts forming an anvil effect during the first step and the second step to finish the bending of the buckle.

Another object of this invention is to provide motivating means for the cutting ofi lengths of wire to size and for the said first and second forming steps.

Another object of this invention is the provision of means employing a covered rod in manufacture of buckle frames or as a part of the decoration of an accessory. Also to act as a fastener for a belt.

Another object of this invention is to provide a mounting for buckle forming dies for buckles made of a cut L length of covered wire without damaging the covering material, comprising an organization of parts including a carrier plate having an elongated slot centrally thereof, two elongated forming dies vertically slidably mounted on the plate, an upright bar mounted in alignment with the slot, the upright bar having a laterally extending member passing through the slot and carrying a horizontally positioned supporting bar for the vertically mounted forming dies, the forming dies respectively carrying two rollers in juxtaposed relation, a mandrel fixed to the front face of the carrier plate, two further forming dies pivotally mounted on the carrier plate below the mandrel and being spring-urged away from the mandrel, the vertical forming dies having bevelled sides contacting the ends of the wire and forming downwardly bent sides, the rollers being positioned to engage the bent sides and prevent rebending of the bent sides, the bevelled sides being in contacting relation with rollers positioned at the upper ends of the further dies when lowered and causing inbending of the bent wire ends into buckle forming relation and with the wire end portions in contact with the lower face of the mandrel, a stripper having two arms and being slidably mounted rearward of the carrier plate, the stripper being spring-urged in a direction rearward of the mounting, the carrier plate having two openings at the vertical sides of the mandrel and through which the stripper arms are movable forwardly to eject the completed buckle, means for moving the stripper forwardly to eject the buckle, and a collector member secured to the mandrel and shaped to direct the buckle rearwardly to a container positioned rearward of the front face of the mounting.

For the purpose of preventing damage to the covering material, I have mounted two grooved and aligned rollers on each of the vertical forming dies, the faces of the rollers being grooved to engage the covering material on the wire of which the buckles are made. The rollers hold the bent Wires of the buckle and prevent rebending of the bent wires and prevent damage to the covering material.

I have also mounted rollers at the upper ends of the further forming dies which serve to inbeud the bent ends of the wire and these rollers prevent damage to the inbent covering material when the covered wire is bent into closing or buckle formation.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 4 is a top plan view of a wire cutting'ofi mechamsm.

Figure 5 is a cross-sectional view taken on line 5-5 in Figure 4.

Figure 6 is an end view of the mechanism shown in Figures 4 and 5.

Figure 7 is a cross-sectional view taken on line 7-7 in Figure 2 and showing a knife actuating arm and a. stripper actuating cam in non-operating position.

Figure 8 is a cross-sectional view, taken on line 8-8 in Figure 2 and showing the vertical forming dies in lowered position.

In the illustrated embodiment of the invention, the numeral 10 indicates a foot pedal operated press of well known form embodying therein a bed 11 and a head 12.

Slidably mounted in the head 12 is a plunger rod 13 which has a reciprocatory movement imparted thereto by means of a foot pedal operated lever 14 which is pivotally mounted on a rod 15 secured in an extension of the head 12. The lever 14 has a bar 16 pivoted thereto on a pin 17 at the free upper end of the lever. The lower end of the bar 16 is pivotally mounted on a pin 18 at the upper portion of the rod 13.

Secured to the bed 11 by bolts 20 are two right angular brackets 21. The brackets have two upright legs 22 positioned in vertical alinement. Secured to the legs 22 by bolts 23 is an upwardly extending rectangular plate 24 facing the front of the press 10.

As best shown in Figures 2, the plate 24 has two arms or forming dies 26 positioned in equally spaced apart relation from a slot 27 at the center of the plate 24 and sli'dably mounted on the plate.

As shown in Figure 1, a T-bar 30 is secured to the lower face of the plunger rod 13 by abolt 31. Secured to the upright portion 33 of the T-bar 30 by bolts 34 is an upright bar 35. The bar 35 has a lateral extension 36 secured thereto by a bolt 37. The extension 36 passes through the slot 27 and carries a horizontally positioned supporting bar 40 which is secured thereto by a bolt 41 passing through the bar 40 and threaded in the lateral extension 36. The bar 40 supports the forming dies 26.

The forming dies 26 respectively carry two-grooved rollers 43, 43. The rollers 43, 43 are positioned to engage a cut to length and bent wire 44 lying on the 3. upper face of a mandrel 45. The mandrel is secured to the front face of the carrier plate 24 by a bolt 46.

Two further forming dies 48, 48' are pivotally mounted toswington the carrier. plate 24 on bolts 49 threa'dedx in. theplate; The further dies 48, 43," and the.* bolts 49" arepositioned considerably'below the mandrel-4 Coil springs 50 have one'end secured: to the'upper end por tions '51 of thefurther forming.dies-48;143' and'have their opposite ends 52 attached to stop plates53 for limiting;,the sideways movements .of the dies. 48, 48. The

plates 53 are secured to thecarrierplate-Z by bolts 54 passing through a tie platez56: It' is toL be noted that rollers are suitably rotatably mounted on the endportions 51 of the forming dies 48, 48

The vertical forming1 dies 26 have beveled lower sides 57 facing, each other. When: the formingadies. 26 are moveddownwardly, thebeveled sides"57 contact both endsof the wire 44-and form downwardly bent sides 58 on the wire 44. Thezroll'ers: 43 onithe formingdies 26- are positioned inxspacedv apart relation' -so as" to engage the bent sides 58 of the wiretand prevent rebending.

or opening up of the bent sides.

Onfurther downward movement of theupright formingdies 26, the beveled sides 57, contact the rollers'55 threaded in the carrier plate 24. The bar63' and the stripper arms 62 areurged by coil springs 65 m'ounted on the bolts tomoverearwardly away from the carrier plate 24.

A cam 67 having an arcuate upper endportion isfsecured to the lower end of the upright bar' 35 bya bolt 68. In the raised position of the mechanism, shown in Figures land 2, the cam 67 has contacted the lower surface ofthe stripper bar 63 and-has moved the said bar forwardly andhas broughtithte stripper arms 62 through the slots 60 a distance sufiicient to engagethe completed buckle and to eject the buckle from themandrel.

Acollector member 70 in the form of a'wire', is secured by the'bolt 46 to'the'central portion of'themandrel 45.

The collector wire 70 is shaped to' direct the finished bucklei' 71' rearwardly of the carrierplate'24to a con-- tain'er: 72 positioned rearward of the front face of the mounting and resting on a sub bed 11.

Figure 4'is a top plan view ofacutting ofl r'nechanism 75 by-means of'which pieces of wire 44 are cut'from' along le'ngth'or from a coil of supply wire. The mechanism' 75 comprises a housing76 having a rectangular cavity 77 in which a knife 78 is resiliently'supported.

As'shown in'Figure'S, the knife 78 is of right-angular form and comprises a horizontal portion 79' which is supported in raised position by coil springsStl against an overhanging bracket 81; The knife 78 also compris'esa vertical portion 83 which terminates at its lower endin an angularly directed cuttingedge'84; the lower end of which is'in line-with the upperisurface of a horizontal feed channel 85 through. which the wire is fed into abuttinglrelation with a stop member 86, shown in Figure 2. A slot 87 permits adjustment of. the member"8'6.

Figure 6 is an end 'view of the cutting ofimech anisrn shown in Figures 4 andS' and showing a release bevel 960m the housing 76.

Figures 2 and 7 show a knife actuating arm 90 pivotally mounted on a. pin"91 in'a bracket '92 which is fastened to'the lower face of an overhanging portion" of a carrier face of the horizontal bar 40 which carries the vertical. forming dies 26.

The arm 90 has a substantially horizontal lower portion 96 for engaging and pressing the knife 78 down into cutting relation with the wire 44, against the action of the springs 80. Further downward movement of the arm 90 causes a bevelled lower surface 97 on the arm 90 10 691186 thbzflifii to Strike the bevelled SUI-15868 96 0111 the hbusin'g'a7'6 and"to slip: an the" knife and to swing away from the knife, which is then brought to -normally raised position bythe springs 80-. A spring urges the arm against theliousing 76.

As shown:in= Figure' 2,-. an upper positioning-block 99 is fastened by a bolt 160.v to the carrier plate 24 and is positioned with its lower surface in" alinement with the upper surface of the wire 44. There has also been provided a retaining bar 101 which is secured by the bolt '46 and extends below theimandreli 45': and. provides a. retaining surface 1 for the. lower bent-portions of: the

buckle and retains them'in alinement.

It will be noted that the knife housing. 76': and the stop member 86 are built with elongated bolt apertures and'are adjustable-to cut andv formubuckles ofvarious sizes. lt will also be noted that the'mountingt may be actuated by a foot power or a hand power press or be motor driven.-

In general the buckle: frame is: formed from 'a rigid:

or. semi+rigid rod which is ornamentally covered: by' a: strip of' fabric having. both: side edges thereof either: sewed together or joined togetherr'by heat and pressure.

InIbending the covered rod, the covering material is formed'to'provide a rib, the: rib being located::within the: confines of the buckle and is 'conti'nuous'andin one plane.

It is -further 'to'ibe noted. that. the shape ofthe: buckle may be'other than rectangular and that'fin all? cases, the" device cuts and formsthe buckle, etc., in oneoperation. It .is also toibe notedv that in the embodiment shown the free'end of the forming die: 48" is --bent'inwardly"to" brin'glits roller in alignment withltheroller on the forming I die 48.
